Vile Gossip | Adventures in tire testing

Jean Jennings has been writing about cars for more than 30 years, after stints as a taxicab driver and as a mechanic in the Chrysler Proving Grounds Impact Lab. She was a staff writer at Car and Driver magazine, the first executive editor and former president and editor-in-chief of Automobile Magazine , the founder of the blog Jean Knows Cars and former automotive correspondent for Good Morning America . She has lifetime awards from both the Motor Press Guild and the New England Motor Press Association. This is her first column for Autoblog — look for more Vile Gossip in the future. I began writing at Car and Driver magazine back in its golden age in the 1970s, before I'd actually read it. I knew very little about cars. The only magazine I read religiously was Four Wheeler because I owned big trucks and liked to go off-roading with my Chrysler Proving Grounds friends. My vast 10 years of driving experience up to that point (high-speed dirt-road idiot, taxicab driver, Chrysler Proving Grounds test driver) had less bearing on my being hired at Car and Driver than the fact that the editor just wanted to rile up the all-male staff. He didn't need me for that. They were already in full dudgeon when I arrived. They'd just spent a chunk of time testing a stack of tires for their big tire-test issue, and the editor-in-chief was toe-to-toe with the technical editor over the rankings of the top 10 tires. It was loud, and it was angry. I had no idea that car magazines tested tires. Cab driving had led me to believe that airing up a tire and changing a flat was all you needed to know. I changed so many flats on that cab, I eventually wound up in front of a live audience on the " Oprah Winfrey Show" demonstrating my brilliance with a jack and a tire iron. My point, of course, is that tires are more controversial, and also more essential, than you'd think. My other point is that it's good to get worked up about the subject, but not quite so good to let yourself be seen, as I did, on my hands and knees with my ass up in the air on national TV. This is how I prefer to test a tire: First, pick a top brand. Then accept their invitation to try and beat the crap out of their tire. I chose Yokohama, celebrating its 100th anniversary this year. The big news for them was the GEOLANDER M/T G003!

Aluminum lightweighting does, in fact, save fuel

When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).

Ford announces recall of 220,000 units in three different actions

Ford has announced three separate recalls affecting 220,000 vehicles built between model years 2011 and 2015. By far the biggest affects just under 213,000 Ford Explorer and Police Interceptor Utility SUVs from MY2011 through 2013. In these vehicles, a spring in the doorway handle could be come unseated, Ford reports, causing the doors to open in a side-impact accident. The affected vehicles were built over a wide range of dates, starting with February 1, 2011 and November 30, 2012. As usual, the majority of the 212,911 vehicles were sold in the US market – 194,484 vehicles, in fact, while Canada and Mexico split the remainder, with 12,392 and 6,035, respectively. The other two recalls focus on specialty vehicles, with Ford recalling 6,500 F-Series Super Duty ambulances and emergency trucks from model years 2011 to 2015. In the case of the 2014 and 2015 F-Series, only trucks with the 6.7-liter turbodiesel are affected. These trucks may have faulty exhaust gas sensors, which according to Ford, could cause the trucks to think they're in a high-temperature situation. The trucks in questions were built at Ford's Kentucky truck plant between February 22, 2010 and February 1, 2015. Finally, the Blue Oval is recalling 1,725 specialty Lincoln MKT crossovers from MY2013 to 2015. These include limos and hearses built between March 6, 2012 and March 4, 2015. Affected MKTs may have a faulty vacuum pump relay that could cause a fire under the hood. In the case of the Explorers, dealers will inspect all four door handles and repair them as needed. The Super Duty's will get software updates, while the MKTs will have the vacuum pump relays replaced outright. A pair of MKT fires has been the only reported incident caused by the recalled components, while the company is unaware of any injuries or deaths.
